well i honestly think watching tapes are essential to the development of any fighter. for one they bascially plug boxing directly into your brain by way of seeing how things happen in the ring, what fighters tend to do, what fighters tend to excel at, and when (and how) they make mistakes. this sort of thing is invaluble; learning the logistics of boxing, as often and as much as you can.

if i may be allowed to give a little promoting here (my check arrived in the mail) go back and read grey's posts on the matter of boxing. nobody has the logistics of boxing down quite as well or presents them in an understandable manner. i myself try but i go off on a bunch of theory type stuff. check his forum out.
